and the upper portions 13 of which are :pivotally mounted'to swingoutwardly together away from the lower track sections 12 in the mannerillustrated in Figs]? and 8. ;F or this purpose, the two upper tracksections :13 are pivotally mounted on pins 1 1 andare provided' withgear segments 16 fixed to the tracks 13 and meshing respectively; withthe worms 18 and 19 onfwOrm shafts 22.and 23. These shafts, are shown asbeing provided with squared ends "for. the reception 'of a prank handle'suchasthat illustrated inFig.

3. The two'worm shafts 22 and. 23 are provided with bevel gears 25 and26: meshing respectively with bevel gears 28; and 2 9,ona shaft 30,'sothat both worms 18 and 19 will'be actuated wheneithershaft 22 or 23isrotated.

The shafts are mounted in suitable bearings which, forthe. sake ofelearness,- have not been illustrated in Fig. 1.

The invention provides locking means for V holding theslintter'sections, in thel'owered position of Fig.1, and, in the presentform,

this locking means is shownas comprising a shaft 34 threaded in abearing35 ,foraxial movement Wlln tlle shaft is rotated. At the forwardend of the shaft 34a locking head 38 is provided, whicl cooperatesQwitha projection 39 .on the iiiner face of the top shutter section ,sothatwhen'the shutter-sections are I V in lowered position, they may belocked from the inside of the house by rotation. of the shaft 34.; p g iThe shutter sections '11(see Fig. 8)'are provided with horizontallyprojecting pins 11" near'tlieir top edges, by which the sections tovidedon-theends ofthesechains so that the are 'connectedto the links ofa pair of parallel-chainsfl liv ,Goiinter W eigl ts 15 are profreeendsof the chains will'ride-cleanof the storage compartment; The lchains 44':- pass over.sprocket.fwheels16v fixed on aligned shafts 19,to "each ofwhiclris-alsofixed a sprocket chain to which is attached thecounterweight 45. moving downwardly until the apart from eachother sothat when the sectionsjare being brought to their lowered pothe chains4A moving vertically in the track members 12 and 13 until they reach thehighestpoint in the sprocket chain, after which they travel rearwardlyand slightlvdown- Wardly as "shown in Fig. 8, the end of the top shuttersection abuts against the rear wall 61 of the-storage compartment 62located above the top of the window frame, and,

I On raising the shutter-sectionsbyfrotation of the shaft 58,fthe upperniost' section begins to movefirst until :the predetermined slack in the sprocket chains is taken up,whereupon the next section begins to move upwardly, theremainingsections following ina similar manner. v

.. The operation of the inventionas a shutter to form a complete barrierfor the window or-a ventilatingbarrier willbe obvious from the flbOVG'ClQSCIfIPUOII.

' Theinvention may be used as an awning,

and. for this purpose, a stop is provided in connection'witli themovable tracks 13. Re .ferring particularly to Fig. '10, the, stop ashereinshown comprises a U-shaped locking pin :7 2, one end of which isadapted to project through an opening 73. inthe track 13;,- andthe otherendfof whiohfpasses through thercylindricalcasing 74: onth'e side-of abracket '75, this end'of the-pin 72 being'threa'ded into a springabutment 76 for cooperation with i a coil spring 7 7 'within'the casing-'74,-so that the locking pin 72 is constantly urged inwardly ortowardsthe window. When-the tracks 13 are intheposition: of Fig. *1, the end ofthe pin Eprojecting through the casing 174 abuts against fixed frame"piece-2 (see Fig. 7;) ,thereby preventing the other-endof theipin fromentering the-openingf 73 in the track 13. If the shaft 22 is. rotatedvery slightly, the tracks: 18 will swing :outwardly'abouutheaxesl'lbyithe mechanism above de scribed, assh'ownparticularly-in Figs. 11- to l' iinclusive. As thetrackslSibegin-tdswing outwardlythe lockinfgpin 7 2 begins toenter theopening 73, being urged in this direction by spring 77, so that bythetimethe' abutment 76 hasleft thememberSQ, the-locking armyojfthe pin '72has entered its-maximum distance into-the-tracl': 1-3,-thereby forming astopmember-for thefllowermost shuttersection, so that if the: sectionsare now l'owered, they will not, enter 1 the track guides 12, i but thelowermost section wil l come toa stop atv the bottom of the tracks13,;--and"the next section wil-l restiupon the first (see-Fig.8).

In the drawings two sections 11- are illustrated as beingsuificientifortheareabetween thev tracks 13, though it is-tobe-underst0od that-any desired. number: ofsectionsrm-ay be used.If'desired,-an abutmenti91 be tions -1-1-so that-when theshaft 22 isfurther rotated to bring thetracksl iiinto-the position cit- Fig; 8,this abutment inelnber =by resting on thenext lower shutter sectionasshownin Fig. 8, willprevent further downward movement of any more":shutter sections thanthe predetermined number desired for the tracks 13,and to "indockingithe, shutter sections in awningposition,

The invention may be used-with hung windows'or with i casement. windows,or sliding windows or doors., ln the event fit is used with casementwindows openingfoutwardliy, thetracks ,13 can be raisedto horizontalposition simply-by continuingrotation. of the shaft 22 beyond the pointnecessary to bring the tracks 13 to the position shown in Fig.. 8,Thefinvention, providesmeans forfpositivd lyholding the gnidetracks 13in raised or awning position, and, as herein illustrated, there areprovided forthis. purpose a pair of track or guide supportingrods 86.,which are pivoted tothe lower or;fixed guides 12 and are connectedto thetracks13 by'brackets 88 fixed to said'tracks and pivotally connected bypins 90to slides 91; these slides riding on theltjrack supporting ro'dsReferring particularly to 'Figsl15 to 17,,the

somewhat greater thanthe width of the rods 86, and pivoted tothe pin950i each slideis a movabletail piece 991 adapted to occupy twopositions with respect tothe remaining portion of the slide.

The pin 90 is adapted to enter notches 101 inithe rod 86 in one of thepositions ofthe slide and to ride past said notchesinanother position'ofthe slide. Forthispurpose the tail piece 99 is provided with-a lu'g103adapted toenter eitheriof two notches 105. and 106 provided in theadjacent side plate 92 and urged in the'direction of these notches-bye.spring 110, which is located between one 'of the side plates'92 and thatsideof the'tail' piece 99 opposite to the lug 103.- i V From theconstruction described it will-be evident that theslide 9-1 is caused totravel toward the outer end of rod 86: as the tracks 13 are raised toawning position. As the 'trac-ks13 are being soraised, the slide isf inthe position of Fig. 16, sothat upon any retrograde movement of thetracks 1:3, thepin 90- will drop into one of the notches 101, therebypreventing further downward movement of the tracks 13. Astheraisingmovetion-lll of the rod 86, causing lug 103 to ride 7 out ofthe notchl05 and into notch .106, thereby bringing the slidepartsto theposition of Fig. 17 Atithis gpointit isevident thatthe bracket 88, whichis attached to the track 13, can move the slide 91 11 further towardsthe outer end of the supporting. rod 86. A cutaway portion 112-isprovided in the tailpiece 99,.which is entered by theipin It now theguide tracks 13 are loweredout ofawningposition, theslide 91Lwill ridedown: the rod 86 inithe position of Fig. 17 in which position it is heldby the" spring 110" so that. the lowerend 10f the .tail :piece 99 ridesover the notches 101, thus preventing the pinfrom entering any of saidnotches.

The slide is moved-upwardly and downwar-dlyiby force exerted on pin 90.At the lowerend of the travel of the slide, a pin H ment of thetracks13- is broughtto aconclua;

sion, the pin 90- is lowered a; sntlicient .distance to bring the partsof the slide to the position of Fig.;;16, so that the lower end of thetail piece .99,being unable to move ;with

plate.92, isibrought totheiposition of Fig. J

tions shown in Figs. 6-and7.

16, that is, the lug'103is caused to ride out of notch 106 and intonotch 105. This movement brings the slide into the proper position 'forthe pin 90 to engage in one ofthe notches 101 upon any downward movementof the tracks 13 after they are again raised to awning position untilthe slide 91 has been brought out to the outermost end of its travel,where it is reversed to the position of Fig. 17, as already described.

Means are provided by the invention for bringing into awning positioncertain awning fringe elements or skirt members 125 (see particularlyFigs. 6 and 7) and for moving or folding these awning elements out ofawning positioniby downwardmovement of the tracks 13 out of awningposition.

' vIn the present embodiment, the flexible awning elements 125' areprovided witlihid= den frame wires 126, which are pivotally mounted at128 and 129 on the track' members 13 so that they can be moved to theposition of Fig. 6or the position of Fig. 7.

vided if desired, which is preferably provided with a more or less'rigidelement 130, to theends of which are fastened pull strings 131 passingthrough guides 132 fixed to the movable track members l3- The other endof each pull string 131 is fastened to the outer end of a lever 133pivotally mounted at 13% on the underside of each track member 13. Thelever 133 is movable on its pivot'with respect to the track 13 intoeither of. the 19051- Ata point 140 on the lever 133, which,-in

the position of Fig.7, approachesrelatively' nearthe guide lug 136,fixed on track 13, 'when the lever is in the position of Flg. 7,

and which point is relatively distant from the guide lug 136 when saidlever is in the position of Fig. 6, is attached. a draw chain 140. Theotherend of the draw chain passes through an eyelet 125 in the awningelement 125 and is connected to theframe wire 126.

It will thus be seen that if the lever 133 occu- V pies the positionofFig. v7, only a relatively small portion of the chaini1 i0;will'liebetween the lever and the lug 136, most ofitlie chain being on the otherside of said lug,

thereby permitting the: awninglelementp125 to hang downwardly in -averticalposltlon. Also, the outer end of'lever 133'hasbeen -.movednearer the 'front awning element so that the length of the draw.string131 be: tween the lever and the draw string guide 132 has beendecreased, allowing' the'front awning element ."125 to occupythe'vertical position of Fig. 7 jVVhen the lever 133 is moved to theposition ofFig. 6', it moves away from the lug'136 and guide 132 pullingwith it the chain and draw string andthu's bring:- ing theawningelements 125 to the position of Fig; 6,"where they liesubstantially parallel to the plane ofthe two movable tracks 13.

similar front awning element may be pro-- The invention provides meansfor moving the lever 133 to the position of Fig. 7 by movement of thetracks '13 into awning position, and for moving the'lever 133 to theposition of Fig. 6 by movement of the tracks 13 out of awning positionand into the shutter position of Fig, 6.

For this purpose, as illustrated particularly in Figs. 6 and 7, the armof the lever 133,,extending beyond the pivot 134, is pivotally attachedto an eye 152 of a link 154, which is slotted for limited movement in avertical plane with respect to a fixed pin 155. f The operation of thismechanism is as follows. Assuming the parts to be in the position' of 6,as the movable track guides 13 are raised to the awning position of Fig.7, the lever 133 is moved in an arcuate path swinging upwardly with theunderside of the track 13. This arcuate movement swings the link 15% ina counterclockwise direction about the fixed-pin'155, as viewed in Fig.6.- The fixed pin'155 is located below and to the left of the' axisabout which the movable tracks swing, asviewed in Fig. 3,'so that as thelever 133 swings outwardly and upwardly, moving the link 154counterclockwise as viewed in Fig. 6, it also moves the eye 152 of-thelink further away from the fixed pin 155 and continues this movementuntil the far-end of the slot contacts with the pin 155, therebypreventing further movement of the eye 152 away from said pin. Continuedmovement of the tracks 13 into the awning position ofFig. 7 results inthe holding of the arm of the lever 133 attached to the eye 152 againstfurther movement away from the fixed pin 155, Consequently, as the pivot134 of lever 133 continues to swing outwardly and upwardly with trackj13away from the fixed pin'155, the forward end" of the lever is moved withrespect to the track 13 from the position of Fig. 6 to the position ofFig.7, and thus causingfas already described, the awning elements125.120 move into awning position.

' When thetracks13 are lowered and are moving out of awningpositiontowards the position of'Fig; 6, the armof the lever 133, which isattached to the eye 152, begins moving inwardly, approaching fixed pin155, and pushing with it the link 15 1 until further movement of'thelinkwith respect'to fixed pin 155 is prevented by contact of the pinwith the end of the slot, after which the eyeattached end of the levercannot move any nearer to the fixed pin 155. Furthermovement downwardly.and inwardly of the pivot v13 1, due to continued movement of thetracks 13 out of awning position, consequently causes thelever 133tomove with respect to the track 13 from the positionbf Fig. 7 to theposition described. 1 7
